Composition including sea buckthorn oil extract and antioxidant and/or a UV filter

ABSTRACT

A composition that includes Sea Buckthorn Oil may be used as a cosmetic product, a pharmaceutical or nutraceutical product or a food product. The composition maintains its distinctive color, due to the use of Sea Buckthorn Oil, over time, even when exposed to oxygen and/or U.V. light. The color of Sea Buckthorn Oil is maintained by adding to the composition Sea Buckthorn Oil in an amount from 0.01 to 90% by weight and an antioxidant and/or a U.V. filter in an amount from 0.001 to 20% by weight.

BACKGROUND OF THE INVENTION

1. 1. Field of the Invention

2. The present invention relates to a cosmetic product an oral ortopical pharmaceutical or nutraceutical product and a food product thatincludes Sea Buckthorn oil extract and an antioxidant and/or a UV filterto maintain, over time, the distinctive color that Sea Buckthorn oilprovides to the product.

3. 2. Discussion of the Related Art

4. Oil produced from Sea Buckthorn (Hippophae rhomboides) berries hasbeen used in cosmetic products, such as, for example, creams, shampoosand gels. Sea Buckthorn Oil is currently produced by two principalmethods. First, is a cold press method where fruit pulp, with or withoutthe kernel, is fed to a centrifuge and oil is separated from theremaining mass. The second method is by extraction with an organicsolvent, such as Freon or hexane. Extraction may also be with aninorganic matter, such as carbon dioxide. The oil produced is sometimesreferred to as Sea Buckthorn Oil, Sea Buckthorn Oil Concentrate or SeaBuckthorn Oil Extract. The oil produced by any of these or other methodswill hereinafter be referred to as Sea Buckthorn Oil. The terms SeaBuckthorn Oil, Sea Buckthorn Extract and Sea Buckthorn Kernal Extracthave been defined in the Cosmetic Toiletry and Fragrance Association(CIFA) Dictionary, the disclosure of which is hereby incorporated byreference. Sea Buckthorn oil has a distinct color that varies fromorange to orange-red. But the amount of Sea Buckthorn oil used inconventional cosmetic products has been so low that the color of thecosmetic has not been altered by the Sea Buckthorn Oil (i.e., thecosmetic product typically remains white in color).

5. In their formulations for cosmetic, pharmaceutical, nutraceutical orfood products, the present inventors have used a sufficient amount ofSea Buckthorn oil so that the color of the final product varies fromyellow to orange depending upon the amount of Sea Buckthorn used. But,in use, the distinctive color that Sea Buckthorn oil provides to theproduct deteriorates or fades over time. The present inventors believethat the color degradation is due to exposure to oxygen and/or UV light.

SUMMARY OF THE INVENTION

6. Accordingly, it is an object of the present invention to provide acomposition for use as a cosmetic product, a pharmaceutical ornutraceutical product or a food product that includes Sea Buckthorn oil,but does not have its distinctive color, which Sea Buckthorn oilprovides, degrade over time, even when exposed to oxygen and/or U.V.light.

7. In a currently preferred exemplary embodiment, the color of SeaBuckthorn oil is maintained by adding Sea Buckthorn oil in an amountfrom 0.01 to 90% by weight and an antioxidant and/or a U.V. filter in anamount from 0.0011 to 20% by weight to the composition.

DETAILED DESCRIPTION OF THE PRESENTLY PREFERRED EXEMPLARY EMBODIMENT

8. The present invention is directed towards a cosmetic product, suchas, for example, a skin care product including cream, gel, lotion orsoap, etc. The cosmetic product may also be a haircare product, such as,for example, shampoo, conditioner, styling gel, etc. The cosmeticproduct includes Sea Buckthorn oil in an amount from 0.01 to 20.0% byweight and an antioxidant and/or a U.V. filter is in an amount from0.001 to 20.0% by weight. More preferably, the Sea Buckthorn oil is inan amount from 0.10 to 5.0% by weight, and the antioxidant and/or U.V.filter is in an amount from 0.010 to 5.0% by weight. Still even morepreferably, the amount of Sea Buckthorn oil is from 0.5% to 2.0% byweight and the amount of antioxidant and/or U.V. filter is from 0.010 to2.0% by weight.

9. A pharmaceutical or nutraceutical product, such as, for example, atopical pharmaceutical product, like a cream, ointment, lotion, gel orpaste, etc. preferably contains Sea Buckthorn oil in an amount from0.010 to 60.0% by weight and an antioxidant and/or U.V. filter in anamount from 0.0010 to 20.0% by weight. More preferably, the amount ofSea Buckthorn oil is in an amount from 0.10 to 20.0% by weight and theantioxidant and/or U.V. filter is in an amount from 0.010 to 10.0% byweight. Even more preferably, the amount of Sea Buckthorn oil is from0.50 to 5.0% by weight and the amount of antioxidant and/or U.V. filteris from 0.1 to 5.0% by weight.

10. For an oral pharmaceutical or nutraceutical product, such as, forexample, a syrup or a mixture, etc., the Sea Buckthorn oil is in anamount from 0.50 to 90.0% by weight and the antioxidant and/or U.V.filter is an amount from 0.01 to 10.0% by weight. More preferably, theamount of Sea Buckthorn oil is from 10.0 to 50.0% by weight and theamount of antioxidant and/or U.V. filter is in an amount from 0.05 to5.0% by weight. Even more preferably, the amount of Sea Buckthorn oil isfrom 15.0 to 35.0% by weight.

11. For a food product, such as a juice drink or a syrup, the amount ofSea Buckthorn oil is in an amount from 0.50 to 60.0% by weight and theamount of antioxidant and/or U.V. filter is in an amount from 0.001 to20.0% by weight. More preferably, the amount of Sea Buckthorn oil isfrom 10 to 50.0% by weight and the amount of antioxidant and/or U.V.filter is in an amount from 0.01 to 10.0% by weight. Even morepreferably, the amount of Sea Buckthorn oil is from 10.0 to 30.0% byweight and the amount of antioxidant and/or U.V. filter is from 0.10 to5.0% by weight.

12. The food product can be used in combination with the cosmeticapplications of the present application. It is believed that when thesyrup or oil is taken orally, the efficacy of the topical cosmetic isenhanced by providing the necessary nutrients to the skin from “theinside”. This type of method of utilizing both a cosmetic and oral foodproduct is known as an “inside-out” method.

13. The antioxidants that may be used in the present invention include,but are not limited to, the substances listed as “antioxidants” in theInternational Cosmetic Dictionary and Handbook, which is herebyincorporated by reference. For example, a natural oil containingantioxidants and some enzymes possesses antioxidant properties.Likewise, the U.V. filters that may be used in the present inventioninclude, but are not limited to, those listed as “sunscreen agents” inthe International Cosmetic Dictionary and Handbook. Additionally, zincoxide and avobenzone may also be a U.V. filter.

14. The following numbered Examples illustrate representative gels orcreams compositions embodying the present invention.

EXAMPLE 1

15. A gel, containing 5.0% (Wt.) Sea Buckthorn oil and no antioxidantsand/or U.V. filters, was kept in the dark at room temperature. Thedistinctive orange color started to deteriorate after one (1) month.After two (2) months the color changed to light yellow-green.

EXAMPLE 2

16. A gel, containing 5.0% (Wt.) Sea Buckthorn oil and 0.5% (Wt.)Tocopherol as an antioxidant, was kept in the dark at room temperature.The gel retained its original orange color over a 2 year period.

EXAMPLE 3

17. A cream containing 0.5% (Wt.) Sea Buckthorn oil and no antioxidantsand/or U.V. filters was tested in the dark at elevated temperature (50°C.) for three (3) months. The cream color changed from golden-yellow tolight yellow in two (2) weeks. In the two (2) following months the colorchanged to white.

EXAMPLE 4

18. A cream containing 0.5% (Wt.) Sea Buckthorn oil and 0.1% (Wt.)Tocopherol as an antioxidant, was tested in the dark at elevatedtemperature (50° C.) for three (3) months. There was no change in colorover a three (3) month period.

EXAMPLE 5

19. Two creams both containing 0.5% (Wt.) Sea Buckthorn oil and 0.1%(Wt.) Tocopherol, one of them with 0.05% (Wt.) Benzophenone-4 as asunscreen, were simultaneously exposed to direct sunlight. The creamsample that did not have a sunscreen changed color from golden yellow towhite after one (1) month of exposure to sunlight. The other creamsample, which includes the sunscreen, retained its original goldenyellow color over the same period of time and under the same exposureconditions.
